T all whom it may. concern:

Be it known that I, HoRArIo ,G. HQUGH- rorncitizenof the United States ofAmerica, residing at Green Bay, .in. the county of Brown and State of Wisconsin, have invented certain new and useful Improvements in Railroad-Ties, of which the following is a specification, reference being had therein to .the accompanying drawing.

The present invention comprises an improvement upon the organization shown in my application No. 40,914 filed July 20th, 1915, which discloses and claims a railroad tie of the general character herein described. The claims in the application are limited to such improvement, or detail structure and arrangement, any broader subject matter that may be read upon the railroad tie herein disclosed being claimed, or to be claimed, in said application Serial No. 40,914.

This invention relates to improvements in railroad ties and has for its object the production of a practically indestructible tie provided with shock absorbing end blocks or rail beds. 7

A further object of my invention is to provide a tie with detachable shock absorbing ends, which ends may be quickly and readily detached and replaced without disturbing the tie proper and without making it necessary to replace the entire tie.

Hereto-fore in railroad ties of this nature, which have been constructed throughout of concrete, molded, in a variety of forms, the

rigidity and non-shock absorbing of the ma terial used, causes the tie to crack which entirely destroys the tie, and in several in stances caused disastrous results. By the use of my improved tie, danger from this source is entirely eliminated, the end blocks being composed of a fibrous material preferably wood which serves as a bed for the rails and to'which they are attached, are joined together by an interposed block of some suitable plastic material preferably concrete or hollow tile. It will be seen that by this arrangement, the wooden bed blocks will efficiently absorb the shocks without danger of cracking the interposed tie.

With these and other objects in "view, this invention consists of certain novel combinations, constructions and arrangement of parts as will be hereinafter fully described and claimed.

Specification of Letters Patent. I Patggntgd figpig, 1 1, 1915 Application filed July'28, 1915. .Serial 110.42,?73.

In the accompanyingdrawings: Figure 1 1s a perspective view of my improved tle,

showing the shock absorbing ends secured thereto. Fig. 2 is a perspective view of my improved tie with the shock absorbing ends removed. F i 3 is a perspective view of a metal plate used in connection with the tie.

Fig. 4: is a perspective view of a shock ab- :sorhingend piece or block which is adapted to-fitto each end of the tie. Fig. 5 is a longitudinal sectional view in elevation of inycomplete tie, showing the rails thereon.

Referring to the accompanying drawing,

v1 represents the tie proper, which is prefferring to Fig. 5, the metal lining plates 1 lie interposed between the rail bed blocks 41 and the tie 1 so as to form a seat for the tongue 6, also reinforcing the ends of the block 1. These end bed blocks 5 are preferably made of wood which has been previously treated by the creosote process for preserving, the wood being an excellent shock absorber will prevent any excessive shock being transmitted to the tie block 1. Tie bolts 7 screw threaded at each end are adapted to pass longitudinally through the end blocks 5, lining plates 4 and tie 1, the threaded ends of the bolts projecting out past the end face of each of the blocks 5 sufiiciently to, allow nuts 8 to be screwed thereon.

It will be seen that by providing the end blocks 5 with a transverse V tongue 6 adapted to fit the metal lining plates 4, which plates fit into the transverse V slots 3 at each end of the tie block 1, a strong substantial joint is produced when the nuts 8 are screwed home on the bolts 7.

The tie 1 being preferably of hollow construction, will be comparatively light and practically indestructible. The end'blocks 5'may be easily renewed without disturbing the tie 1, to do so, the nuts 8 are removed, the blocks 5 may then he slid away from the block 1', new blocks can then be'placed therei in and the nuts 8 again screwed home on the bolts 7. V

'By this arrangement it 'will be seen that a very simple, cheapv and durable shock absorbing tie has been produced, and that the renewing .of the end rail bed blocks 5 can I be quickly and cheaply accomplished.

- laving thus described my invention, what .1; A tie comprising an elongated block of plastic material,v shock absorbing means adapted to form a bed for the rails secured adjacent each end of said block, reinforcing said shock absorbing means, and means for securely joinlng the said parts together.

2. A. tie comprising a rectangular hollow block composed of plastic material, shock 25 for securely joining the same together.

8. A tie comprising a rectangular hollow block composed of plastic material and having transverse V shaped slots in the opposite endsthereof, reinforcing metal V plates adapted to fit in said V shaped slots, shock absorbing rail bed blocks composed of a fibrous material having V shaped tongues thereon adapted to lit in said reinforcing plates, and a plurality of tie rods or bolts for longitudinally joining the said parts together. means disposed intermediate said block and V In testimony whereof I hereunto afiix my signature.
